Ok, but in that case the compiler should say something to the user.  Rejecting
such a code could be a first step.

However, in general I think that the compiler should analyse the code and
figure our which instruction suits in the given situation.  If alignment can be
evaluated -- aligned move, unaligned move otherwise.
